Be it known that I, llrznnnur Smxnrzr Bnowx, e citizen of the United States, residing in New York city, borough of Mlnlmtten, New York, have invented eertnln new end useful Improvements in Oseillnting Electric Fans, of which the following in n peciticetion.

The object of my invention is to provide im le and etllelent menne for censuur the onei hn ion of en electric fen, end in eurryiun out my invention I pivotelly support the fnn und embody ineens for resisting rotary movements of the fen ntrueture, whereby sueh resistauu'e resets end causes oseillntions of the fau. In one form of my invention l eonnect the fm structure with un overhead support b an interposed llexihle eonnection capable o being put under torsion, whereby as the fen turns in one direction the supporting connection will be wound, the rem-tion of which otter momentum dieu ont will euuse the fun to move in the op insite direet iou with holler mult otter ming thenornml point or the point ol equili rium, und so on oseillnting h nck ond forth an the hm hlndes rotnte. l This tohiionnl support muy I,e in the form ol one or more llexlhle strands or strings capuhle of twisting and untwisting in op|umite directions. l

The invention also comprises the novel details of impmvmnent that. will be more fully hereinafter set forth and then pointed out iu the eluitns.

Aa a convenient means for connecting the nu port 4 and conductor t2.` with the shaft 5 ave shown said shaft as split lo itudinally and the ends of the support conductor placed therein, the nut 7 aerving tc squeeze t e members of the shaft 5 u n the en port and conductor.

Fig. I nave ahown a ditl'erent form of raaotional up rt for thtI fan, hat one aet in ln a manner a milar to that above describet with respect to Fig. l. ln this ease the snprt 4, is pivotally connected with the hanger 3 b means of a universal connection, permitting the fan to oaeillate or swing back and forth aa may bc required. la thc form chown I have provided antifriction-bearings wherein a hemisphere or the like 25, sweartal to therod-aupport 4", rests upon balls 26, earried by a cup Z, cotmected bv a yoke 28 with the hanger 3, the threaded stellt 28' and nut permitting eonmaetion of the yoke with the hanger, and at 3u is'a coiled spring oonnecttsl at one end with the support and at the other end with the yoke 2n, which spring may be in the nature of n clock-spring norlnallv not under tension. The opening 27 in the cup .27 is of sullicientsize to permit the support 4" to swing freely, and tlte hemisphertcal surface of the member serves to permit tbc fan to have universal as well as oscillator)y motion. A nut 2n on snplmrt 4' perauts vertical adjnsnucat of the fttn with respect to its su lpott. With this form of sup ort for the in thc latter vill o rate in t te tnanner similar to that deecri ed with respect to Fig. l, the twisting and untwisting of spring 30 serving in manner similar to the twisting: and nntwisting of the flexible support 4 to produce the required toraion to cause the continued oscillations of the fan.

My invention is not limited to the particular arrangements and details of construction 'shown and described, as the same may be varied without departing from the spirit thereof.

Having now described my invention, what I claim is l. 'lhc combination, with a fan having its' axis placed at an angle to the vertical and arrttned to deliver a stream ofair in the gcnera direction of said axis, of un electric motor therefor and a suspending device having means for prtalucinfg torsional reaction to the movement of the an about the sat-minding device as a pivot, whereby variations in the current sup lied to the motor serve to maintam oscilla ion of the fan, substantially as described.
